the kernel is fine, the filesystem optimization not working fine with the old version of the CWM.

just give me a minute that i install the old 5.0.2.0 cwm and see what is the unsupported feature.

the strange thing that im installing the cmw 5.0.2.0, then flash cm7 kang and the kernel and booting :)

however here is a fix what is remove the unsupported features, it might be help: http://www.donka.hu/android/fix_ext4.zip

if still not working try this: http://www.donka.hu/android/0-full_wipe_0.3_ext4.zip

this will do a full reformat on every partition with ext4 filesystem.

updating the cwm installer that not using the unsupported flags, its compatible the old cwm now
[LG Optimus 2x] sunstorm:
Hi Vadonka,

I installed cwm 5.0.2.7 r2 (Rusty's) just to try out your kernel and the device still refused to boot up.
[LG Optimus 2x] vadonka:
redownload the cwm zip and try again

install cm7 kang, gapps, then the kernel, dont reboot

i need the recovery.log file

plug in the usb cable then

adb pull /tmp/recovery.log

attach this file to here
[LG Optimus 2x] drigerott:
the problem is /system

after i flashed your kernel, cwm can't mount /system anymore..
[LG Optimus 2x] vadonka:
try the kernel only update what i posted before. this is not toch the system.

but im updatig the cwm zip with a safer filesystem flags you need to redownload.

the hard thing is that i cant reproduce this problem, i try to install the cwm 5.0.2.0 and everything is working with that too.

after installing the update try this from the adb shell:

e2fsck -fy /dev/block/mmcblk0p1
[LG Optimus 2x] andy010101:
Clockwork mod cannot mount system after i flash your kernel.

Flashing the kernel only version works.
[LG Optimus 2x] vadonka:
i removed the filesystem optimization part from the cwm update for now.

lets see with this working for everyone.

the good thing is the main kernel is fine :)

the update-binary file have a many version, i think its safer that minimize the use of this, and using the busybox for everything.
[LG Optimus 2x] andy010101:
it works now , im am glad that after you worked so hard on this kernel , it has finally come together :) Thanks
[LG Optimus 2x] salisbury_steak:
The OP says that it was updated 5 hours ago. Did I miss the new and improved package somewhere? :confused:
[LG Optimus 2x] new2city:
Trying the memory shared version with battery saving, so far so good.. But I am also what are the additional benefits removed to solve the initial problems faced early..

I was lucky, I was still sleeping when you guys were trying out the first released.

Still, good job and thanks for the effort..
[LG Optimus 2x] antec123:
finally, your kernel is released, will try the UV+32mb memory hack hope it's not giving SOD

so for confirmation, that the UV kernel will default voltage already undervolt right??

and it's nice you fix the audio driver so the sound on right earphone and left earphone is balanced.
[LG Optimus 2x] salisbury_steak:
Using the 32mb UV kernel from OP now. Working really well so far. Thanks very much Vadonka!

Sent from my Optimus 2X
[LG Optimus 2x] vadonka:
no need, wiui have the bravia hack by default
[LG Optimus 2x] vadonka:
already done, its working on my phone now :)

tomorrow i will update the OP

but now im go to sleep :)

bye
[LG Optimus 2x] mrmaffen:
is it just me or are the servers hosting the kernel files down?
[LG Optimus 2x] :
It is extremely slow and not able to download, I was doubting my network!
[LG Optimus 2x] owain94:
i got a download speed of 3.2kb/s on a 200MB/s connection :o

yesterday downloaded the file within 1 or 2 seconds so yeah it must be the host
[LG Optimus 2x] crankyboy:
Me too. Getting 2.7kb/sec

And im using turbo download manager with 10stream lines open..

Bahhhh
[LG Optimus 2x] sushantp666:
Hey vadonka this kernal is quite good also stable,Thanks for this.

I have some issue with cm7, I don't know exactly is it rom prob or kernel, I m not getting full speed over USB mass storage, say its giving only 33% of total speed.so any remadies for this?

Well thanks again for kernel :-)
[LG Optimus 2x] grognaz:
got some freezes with the test kernel:( is there still undervolting in it?
[LG Optimus 2x] vadonka:
no, every voltages around the safe value, maybe only the lowest value...

216mhz using still the 770mV

i think i rise this value to 790mV... by the way im using this value one of my older version.

what i used now, every values can be undervolted by 20-30mV if the phone supported it.

im adding back to the sched autogrouping support, its become handy and not doing anything wrong.

so 216mhz adjust to 790mV, and build a few ramhack version and 16/24/32 bpp mode.

today i will update the OP.
[LG Optimus 2x] vadonka:
its sound like related to the sdcard

use the 'sd tools' app from the market and test your sd card read/write speed.

im adjust the read_ahead level to better performance, but every sdcard is different.
[LG Optimus 2x] grognaz:
hmm that was usually the only value that worked, but its worth a try...
[LG Optimus 2x] vadonka:
the lower freq's are more sensitive than the higher. so in 216mhz +-10mV can may help or worsen the stability
[LG Optimus 2x] plakers:
testing this new one... (under CM7/Kang) - the previous one (stable 0M) gave me short battery life :( but was rock stable & responsive

thanks for your work, i'll give you a feedback with my classic -25 undervolt to all freq (wow! as i'm writing, first bsod after my first boot lol)

:)
[LG Optimus 2x] vadonka:
be carefull with that undervolt :)
[LG Optimus 2x] plakers:
ok, the first "bsod-like" was just a big lag, no crash with the new test version, even with the -25 to all freq. (for info : setcpu profiles with screenoff @216-503 range)

so no problems for the moment, it's seems everything is stable

do you recommend a specific BB/RIL combination for Kang and that Kernel? read some posts on others topics that gives 824 a big battery life improvement, any feedback? (i'm on 725)
[LG Optimus 2x] vadonka:
its highly depend from your phone hardware

for me only the 503 or earlyer or the 824 work. 622, 725, ... all of them provide a terrible in call voice quality.

im on 824, best so far.

i think the 823(P990) or the 824(SU660) is a good choice.
[LG Optimus 2x] Platoon:
New test version is not really stable. I have korean phone, i am using 824 which works great with my phone, but this morning i got strange error. I was browsing using dolphin browser. I pressed softkey for keyboard and bam, phone started to vibrate and screen became unsresponsive. I had to pull out the baterry.

Strange! I never had such problem with your previous kernels.
[LG Optimus 2x] fuxmen:
the 4 test version is ovesome, full stable for me, and battery life is very good with wifi always on and data :) thanks a lot waiting for more :)
[LG Optimus 2x] emoriatov:
I can´t seem to find bb 823(p990)anywhere, does anyone have a link for it?
[LG Optimus 2x] plakers:
strange symptoms for me, but happens few times :

1) battery still drains, even while charging, and phone is not running any app...

2) my cpu/battery temp seems to be higher : may be a background task related to the above problem... (but screenoff and voltages are low, strange)

didn't install any new app, changed any setting etc... since I installed the new test kernel (but the perf/battery seems good)

CWM RIL: http://www.mediafire.com/download.php?dnkav301qt195mq
[LG Optimus 2x] silentmelodies:
Yep, it's been very stable for me too. Looking forward to a 32MB shared ram version :)
[LG Optimus 2x] vadonka:
test version 4 modifications:

-adjust 216Mhz min voltage from 770mV to 790mV

-enabled memory compaction and sched autogroup

currently building

no ramhack: 16bpp, 24bpp, 32bpp

32m ramhack shared: 16bpp, 24bpp, 32bpp

32m ramhack: 16bpp, 24bpp, 32bpp

48m ramhack: 16bpp, 24bpp, 32bpp

64m ramhack: 16bpp, 24bpp, 32bpp

80m ramhack: 16bpp, 24bpp, 32bpp

96m ramhack: 16bpp, 24bpp, 32bpp

it will take a while...

automatized builder working, im going to lunch now :)
[LG Optimus 2x] Schmeichel1:
Hi,

When i use GetRIL app to change RIL and change it to 824(SU660) it's showing that "Your RIL and Baseband doesn't match" ... what to do with it "Ignore" or change for matching one ???

PS. WajkIUI kernel works fine for me no problem for now. Very fast stable at 1,4 Ghz :) and good battery life.
[LG Optimus 2x] vadonka:
getril doesn't recognize the baseband 823 and the 824

i posted a cwm update, just flash from via cwm

or use 'lge ril' app what can recognize the newer baseband
[LG Optimus 2x] silentmelodies:
It's a good thing that you have an automated builder, but.. is there really any need to make that many ram hack versions? :p

0, 32s/rh, 64rh, 96rh, should be enough, I think. But anyways, keep up the good work :)
[LG Optimus 2x] vadonka:
its automated, so i just need to push the enter button :)

even create the cwm update zip too :)
[LG Optimus 2x] vadonka:
here is the patch what is needed for the shared memory version working well, differ with cm7 git

someone asked this :)
[LG Optimus 2x] notthesun:
i'm using getril with bb 824 and it works good...
[LG Optimus 2x] fuxmen:
waiting for 64mb ramhack version :) thx a lot for that
[LG Optimus 2x] Thronesmasher:
I got 2 crashes with the 26 MIUI test version today

I hope the new version you're working on will fix this
[LG Optimus 2x] _Vegas:
Waiting~~~~:D
[LG Optimus 2x] jefbeck:
the january 19 32mb normal version is the best for me. no abnormalities, as in 100% stable so i will be sticking to it unless otherwise vadonka will release another kang much more better to it.
[LG Optimus 2x] 4lph4:
:eek::eek:

Really impressive!

Now I have to decide what to test during the weekend :) Too many choices.... :confused::D

What do you suggest as bpp level?

I'm thinking that more bpp means more memory reserved for the graphic part. The higher ramhacks could have problems, what do you think?
[LG Optimus 2x] vadonka:
bpp is the default color depth (bit per pixel).

default this value is 16.

by the way, kernel is updated, see in the OP
[LG Optimus 2x] hkkp:
Both CM7 and W versions are working fine with MIUI-2.1.20, very smooth. Seemed deleting scripts in init.d didn't cause problem with MIUI, now I am stick with CM7 version.
[LG Optimus 2x] vadonka:
the miui have some tweak init script what is made for the miui and its probably needed. this files deleted too

you better that use the miui version :)
[LG Optimus 2x] plakers:
OK, let's try the 32M one... with 24bpp ;)

(the default kernels are based on 16bpp?!)

Thanks for the job Vadonka!

feedbacks will come soon ;)
[LG Optimus 2x] vadonka:
if your phone is sensitive with the low voltages its possible

the new version what is released now have a bit higher minimum voltage

216Mhz voltage 770mV raise the 790mV

as i see in other forums too, its helping for some people that eliminate the bsods
[LG Optimus 2x] silentmelodies:
Yep, me too :)

Is 16 default for CM7 only or is it the same with MIUI based Roms? Because I think the bppi in MIUI is already high and there is no noticeable color banding issue, unlike CM7. I could be wrong though.

And does more bppi mean more work for the GPU and is there any impact in performance?
[LG Optimus 2x] Thronesmasher:
could you add the youtube fix to the miui release?

setprop ro.build.lge.version.release LGP990-V201

20120127-1201-LGEK-RH0M-16bpp_wiui boots fine, running well so far
[LG Optimus 2x] vadonka:
if i have some time i will merge this two installer that determine the rom version and run the rom specific installer process.

then it is no need to separate the two installer.

by the way there is a mess in the wiui init script. using the juwe ramscript and some other tweaks, then applyed mine. my init script will override any previous sets so its not needed.

i will improve the installer to handle this... soon :)
[LG Optimus 2x] Stefan Gündhör:
Making hybrid things is getting quite popular at the moment :D
[LG Optimus 2x] fuxmen:
64 mb 24bpp wont boot for me restoring backup with yesterday version

after restore can't start ;/
[LG Optimus 2x] tonyp:
damn.. now I got a charging bsod.

I NEVER had one of these before. It seems that my phone doesn't like undervolting and underclocking a bit (it's a Korean one).

is the new modified test version exactly like the CM7 one in terms of voltages?

if not - could you provide one with the same values like CM7 - the CM7 kernel is rockstable for me (but the sensors and battery life is worse than with yours).
[LG Optimus 2x] vadonka:
try with the 32mb ramhack. not every ramhack working for everybody. its strange but true. another mistery of this phone :)
[LG Optimus 2x] vadonka:
this version is identical like the test 4 version

i just enabled the memory compaction option in the kernel and the autogroup scheduler, but its not related to the charge bsod.

the only voltage modification is what i write before: 216Mhz 770mV raise to 790mV
[LG Optimus 2x] tonyp:
No, I got this charging bsod with the version from yesterday (without the modification).

do the voltages differ from the cm7star kernel?

and I can't believe you didn't give up already with all that different hardware - you're putting so much effort in it - amazing! thanks a lot for your support to make the o2x a better phone :)
[LG Optimus 2x] mrmaffen:
ive tried your kernelversion 20120126-1644-LGEK-RH0M.zip and got a bsod just 5 minutes ago while the phone was sleeping.

now im going to try your newest kernel version: 20120127-1201-LGEK-RH0M-16bpp.zip

im using bb/ril 218 with quite nice battery consumption (6% in 8 hours). hopefully i will finally get rid of the bsods with your new kernel.

can you explain in what case it is usefull to switch to 24bpp or 32bpp? also it would be nice to know if i should use your 0 MB ramhack version or try another one? what are the pros and cons?

thanks for your work! :)

ps: i can highly recommend to use a density value of 194. got no graphic bugs so far.
[LG Optimus 2x] vadonka:
the yesterday version have a 770mV on 216Mhz, and as i see in other forums while the phone in charger, sleeping and the cpu clock is stick at 216Mhz its causing issues on some hardware if the voltage is ~760-770mV, thats why i raise the minimum voltage to 790mV. +-10-20mV doesn't affect the battery life but the stability yes.

so try this version what i released a few hour ago

i dont give up because im working in the IT sector and i like this, its helping me to be a smarter and better IT specialist :)

and about this community, i dont force anyone that push the thanks button but im already over in 400 :) thank you guys!
[LG Optimus 2x] fuxmen:
its strange but even yesterday version won't work now for me

and 64 ramhack works couple days ago it isn;t it, now i flash pure kang with kang kernel system boot up, I like very much Your kernel because battery life is just owesome! will try more later
[LG Optimus 2x] vadonka:
after a some rom/kernel reflash you cant avoid the full wipe or else you will have some strange problem :)

i know that because im reflash my phone at least a hundreds of time and i see some very strange things sometime, but after a full wipe everything is perfect :)
[LG Optimus 2x] ron_gangte:
Using 24BBP 32MB Shared Memory version.

Tasker does not work. :-(

Vadonka, please provide a quick fix. :-)
[LG Optimus 2x] rskyline:
Vadonka thanks for releasing 24/32BPP Versions! What about 32? There are stable?

Enviado desde mi Optimus 2X usando Tapatalk
[LG Optimus 2x] Pacas:
Vadonka could you please write a guide or something explaining about the differences and info about the kernel versions for the noobs (Like me), maybe post on your first post, so it will be easy to find and no one will ask again, cuz i have searched and cant find a straight and complete answer in this thread :(, would be very grateful

general questions:

-explaining how it works, differences, shared version or not? Which should be more stable/ has less bugs and missing stuff, battery, performance? with higher MB less stable? bpp etc

As I understand it can be different for all, but just general info on these topics if possible, would be very nice :)

Ok but with cm kernel everything works ;/ maybe i will doo full wipe but not today :)
[LG Optimus 2x] ergoen:
Thanks a lot for your awesome work vadonka!

I tried flashing both the 24 and the 32 bpp versions of your kernel, but neither of them seems to remove the banding in my background-image and in the background of the gallery app. (Viewing the same background-image file on a computer shows no banding). Do I have to enable the higher bitrates somewhere in the rom as well?
[LG Optimus 2x] vadonka:
i dont know, but the kernel supported the 32bpp version

but its possible that the cm7 rom override the bit per pixel setting, its not hardcoded into the kernel.

i just modify the default bpp value
[LG Optimus 2x] plakers:
+1... have to update my baseband to 824...

but not today ;)
[LG Optimus 2x] rskyline:
Same here so maybe is CM7 that maybe don't support 24/32BPP so we have to go to temasek thread and ask it ;$

Enviado desde mi Optimus 2X usando Tapatalk
[LG Optimus 2x] ergoen:
Ok, about the bitrates:

I've created a 24-bit gradient image that should have no banding:

https://ha.xxor.net/o2x/gradient.png

In the web browser with the 32bit kernel it looks as it should. Downloaded the image to my sdcard and viewed it in the gallery app => severe banding! My conclusion is that the android/cm7 gallery app cannot show more than 16 bits, so it's not the kernels fault!
[LG Optimus 2x] vadonka:
bpp can be change realtime. chainfire 3d can unroll the textures to 32bit, so it is can be change from the rom somehow.

like the right click/properties/display in the windows :D
[LG Optimus 2x] mrmaffen:
ive just tried your newest kernel 20120127-1201-LGEK-RH0M-16bpp.zip and noticed some extreme battery drain while in standby. also ive noticed a major wakeup-lag from time to time (about 2 seconds). also the wifi connection wasnt disconnected although my wifi policy setting was set to do so.

im trying to do a complete wipe now and reinstall the latest kang with your latest kernel. will report back with my test results
[LG Optimus 2x] _Vegas:
So, the 32bpp version is the best?

It will lead to lag？
[LG Optimus 2x] rskyline:
So what do you recommend??

Enviado desde mi Optimus 2X usando Tapatalk
[LG Optimus 2x] rskyline:
Do you think that a geforce will lag? With this gpu you can boot a entire Desktop Computer, I've used 24bpp kernels on spica and ran ok here will be better

Enviado desde mi Optimus 2X usando Tapatalk
[LG Optimus 2x] tablerone:
All is running ok with the 24bpp RH32MB at MIUI included Tasker.

Thanks a lot vadonka. A awesome job!
[LG Optimus 2x] :
Flashed 32bpp no ramhack and everything seems fine. I would like to know what is the overhead in using higher bpp. I just flashed 16bpp and it works fine. I am not sure how to see the difference...
[LG Optimus 2x] vadonka:
the higher bpp is using the same kernel build, i just update the kernel boot argument that adjust the default bpp, but it seems that the cm7 will override this and still remain in the 16bpp, so it does not matter what you used.

somebody need to investigate the cm7 source about the default bpp :)

the kernel loaded first and may be adjust the bpp to 32bit but then the rom loaded and it revert back to 16bit. its highly possible.
[LG Optimus 2x] mrmaffen:
tried a complete wipe, isntalled temaseks kang 48, installed your newest kernel, got exactly the same issues. extreme battery drain, wifi not turning off while sleeping, major wakeup lag. also the device is getting quite hot.

i will revert to your 20120123-1754-LGEK-RH0M.zip kernel, although i had bsod issues with this one.

greetz
[LG Optimus 2x] ergoen:
CM does support higher bitrates! It's only certain apps that do not (eg. Gallery app), see my previous post! (Compare https://ha.xxor.net/o2x/gradient.png in the browser vs the gallery)
[LG Optimus 2x] vadonka:
do you have any system monitor app like system panel? id like to know the cpu is stressed or not? and a better battery stats also be usefull that see what causing the wakelock.
[LG Optimus 2x] fuxmen:
full wipe, 50 kang 0,32,64 mb 16bpp nothing work... have enought of this :( too bad because test version work whole day but now cant boot, LG logo and shutdown on every version
[LG Optimus 2x] mrmaffen:
i just bought the system panel app. will report back with more detailed stats
[LG Optimus 2x] sergiob8:
I had 2 reboots yesterday with Miui and 26 version, so I flashed WajkIUI with kernel 26 too and no problem at all. Today, with version 27, everything is just perfect.

Thanks again for all that work!
[LG Optimus 2x] jefbeck:
im using latest vadonka kang with 48mb ramhack 32bpp, all is well for now. i will report if i found something annoying.
[LG Optimus 2x] fuxmen:
I need to stay at stock CM kernel :( why I have bad luck :( tried already even 26 jan 23 jan version every time the same or shutdown or black screen with light on

jefbeck -> You just instal it and it work?
[LG Optimus 2x] vadonka:
if nothing can work try this: http://www.donka.hu/android/kernel/test/20120127-1651-LGEK-RH0M-16bpp.zip

its a same version what i posted today just disabled the autogroup scheduler.

i can harldy believe that ist the problem, but never know :)
[LG Optimus 2x] fuxmen:
what about memory compaction maybe that is problem for me?
[LG Optimus 2x] Thronesmasher:
meh, first crash with 20120127-1201-LGEK-RH0M-16bpp_wiui
[LG Optimus 2x] mrmaffen:
after i reverted to the older kernel ive noticed that my problem wasnt resolved again. from what i can see just now, the cpu usage when in standby is permanently like 10%. battery temparature is ~35°C.

this smartphone is starting to really piss me off. just 2 days ago i got it back from the repair centre. and still this issues are not resolved.
[LG Optimus 2x] Higgsy:
yay! Vadonka kernel works again (24bpp no ramhack) Thanks!
[LG Optimus 2x] vadonka:
i dont think so but if you want i will compile a version without the memory compaction

but i think the major problem was the undervolt
[LG Optimus 2x] fuxmen:
im on ironkernel now with 775mV and no problem with boot...
[LG Optimus 2x] grognaz:
welll these last versions didnt work out for me, highly unstable, so the voltage is definitely not the (only) problem. back to 09.01....
[LG Optimus 2x] rokasjasonas:
updated kernel and temasek rom (first rom, then kernel) and now I cant oveclock my phone. Updated kernel to 32mb hack, 24bpp
[LG Optimus 2x] grognaz:
so far the 1651 version lasted longer than any other... still no freeze, so maybe this one works...

i will report back later if it crashed or not.
[LG Optimus 2x] jefbeck:
not just install..

what im doing is wipe cache partition, wipe dalvic cache, then flash it, then reboot and add some patience. once i passed the lg logo with colors and the boot animation, it will stay on black screen but when i touch the screen, the led buttons will light. then just wait about a minute then its ok. then i reboot again.

i hope i helped you.

PS: do not wipe data or factory reset. this was my mistake when i was still very very very noob. (now only noob, not so very) ;-)
[LG Optimus 2x] fuxmen:
ok i will try because i wont clear cache and dalvik befo install never.. and on my phone don;t see even LG iwth colors only first then nothing...

my phone just shutdown after firs logo ;/

I like this kernel very much but not my phone :(
[LG Optimus 2x] Higgsy:
Bummer, 2 BSOD within 30 mins on 24bpp no ram hack kernel. :confused:
[LG Optimus 2x] fuxmen:
it's not that bad :D mine wont boot on any version and shut himself down ;D

cheers

Vadonka whats up are U doing sth with this?

Have beer or two from me please work around this :) will be more if this work for me :)
[LG Optimus 2x] Shadowchaz:
